Thanks guys; been busy for the holidays. Real vids are coming someone I know must have a video camera. Engine Management uses the Chevy LSx computer, in this case I believe it was from a Chev LS based truck. The harness is all wired in, no check engine lights or Christmas tree cluster.

Same sizing for exhaust Magnaflow uses; don't think its a problem. No back firing or any other exhaust related problems thus far.
